The prices of both CNC motors are very reasonable, but the price of stepper motors is usually lower. Even if the servo motor and the stepper motor have the same rated power, the price of the stepper motor is usually lower. Stepper motors are easier to find, so they have more features.
Stepper motors are incredibly versatile, which makes them very popular among hobbyists and industrial applications. Stepper motors can be found in thousands of products from personal computers to automobiles.
The reason why stepper motors are more reliable than servos is that stepper motors do not require encoders. Servo motors are also very reliable, but they require an encoder that is known to fail.
The noise generated by the servo motor is very small. Due to the control process, the stepper motor will produce a slight buzzing sound. However, high-quality drivers will reduce the noise level.

The servo motor is very efficient. Under light load conditions, the efficiency can reach 80-90%. Stepper motors consume a lot of power to output, a large part of which is converted into heat. The efficiency of a stepper motor is usually about 70%. This is also a great feature to help you decide which one to choose.
In general, the design of servo motors is more complicated due to internal parts and encoders. Stepper motors are easy to use and easy to understand, thus winning the field of motor design.
The brushes on the servo motor must be replaced every 2000 hours of operation; in addition, the encoder may need to be replaced. The bearing on the stepper motor is the only vulnerable part, which slightly reduces the service life of the stepper motor.
